An object of therpresent invention 1 islth'e provision of a double saiety razor bladeiwhich. cone sists of the blade proper and its support, and which is so constructed that the blade will be quickly and easilyreleased from its support and deposited upon the safety razor.

Another object is the avoidance of any delay or inconvenience in releasing the blade from its support when the blade is deposited upon the safety razor. I

A further object is the provision of a bladesupport which is so constructed that the blade may be easily released from its support by the fingers of one hand.

.Other objects will be apparent in the course of the following specification.

The above and other objects of the present invention may be realized through the provision of a blade support which in itself is not bent or moved when the blade is released, the releasing of the blade being carried out by moving the blade away from the support or by releasing avoided.

figure-3 is a perspective view or a. double blade comprising a support provided with separate bladeeholding' means; and V Eigurentis a section along the line 4-4 of Fig- UIJEBQ P i Thesafetyi razor blades used in connection with-the present invention may be of anystandardforih, although in certain instances it is preferred to employ blades provided with; two. sharp cutting edges and two tongue'porti'ons formed by the dull edges of the bladetand separated by shoulderstrom thecutting edges. I

The blade supports may be. made of cardboard onpf anymther suitable fibrous and/.ortflexible material. preferably be made of a hard, resilient substance, sm'ihyas a metal or metal alloy, for example, steel or: the like. "The? support should be: wider than the: bladcs in ndento protect-their edges as 1 well asthe fingersfof the user... T

The surfaces of the blade support may be w-aterproofed and rustproofed by waxing or by any otherappropriate means.

The device shown in Figure l of the drawing comprises a razor blade 5 having two sharp edges 6, two tongues 1, and a central opening 8. The blade 5 is carried by a blade support 9 having the form of a rectangular frame which consists of two elongated side portions I0 and II and two shorter supporting portions I2 and Ill. The frame of the blade support 9 encloses a central, preferably rectangular, opening M, which should be sufiiciently wide .to provide a space between the inner surfaces of the'side portions l0 and Hand the sharp edges 6 of thablade 5. Thus any contact between the edges 6 and the support 9 is The inner surfaces 15 of the supportingportions I2 and I3 of the blade support 9 are provided with grooves l6 and I1, respectively, which In some instances; the support should are somewhat wider than the tongue portions 1 of the blade 5.

As shown in Figure 1, the blade 5 is connected with the support 9 by introducing the blade into the opening M of the support 9 and by inserting the tongue portions 1 of the blade 5 into the grooves l6 and H of the support. Due to the provision of these grooves the blade 5 will be held firmly within the support and any danger that the sharp edges of the blade may be dulled or that the user may be injured is avoided.

In order to use the device, it is merely necessary to place the support 9 carrying a blade 5 over the supporting surface of a safety razor not" shown. The user may hold the safety razor in one hand while two fingers of his other hand hold the support 9. When the blade is located in its tions 1 are Withdrawn from the grooves l6 and I1. Then the blade 5 is released so that it can drop intoits proper position upon the safety razor. I

The device shown in Figure 2 of the drawing comprises a safety razor blade 5 carried by a blade support I8 consisting of a fiat, rectangular sheet which is wider and longer than the blade. The blade 5 is held upon the support l8 by means of two flaps or tongues l9 and 20, which are preferably cut out of the support 18 and which may be arcuate in shape. The flaps l9 and overlap the tongue portions 1 of the blade 5, thus holding the blade firmly upon the support I8.

The flaps l9 and 20 should be sufficiently wide to bend easily in a direction away from the supporting surface of the member l8 when the user desires to release the blade. For that purpose the edges of the support l8 may be provided with notches 2| which will facilitate the bending of the support IS in such manner that the flap 19 and/or the flap .20, is.bent away from the supporting surface of the member l8.

It is apparent that the blade 5 is released from the support l8 by; the application of pressure against the support l8 in such manner that the flaps l9 and 20 either. simultaneously or alternately are moved or swung in a direction away from the supporting surface'which carriesthe blade 5..

The device shown in Figures 3 and 4' comprises a razor blade 5'situated upon a sheet or support which carries two blade-holding levers and 26. The lever 25 is pivoted to the blade support 24 at 21 and comprises a flap portion 28 which overlaps a part of one of the tongues 1 of the blade 5. The other end of the lever 25 extends over a cutout portion 29 of the support 24 and preferably constitutes a continuation of the edge 30 of the blade support 24.

The lever 26 is substantially similar in construction to the lever 25 and comprises a portion 3! which extends over the cutout portion 32 of the support 24. Springs 33 and 34 are used for the purpose of holding the levers 25 and 26 in the position shown in Figure l.

The mode of operating the device shown in Figures 3 and 4 is as follows:

The user may hold the safety razor in one hand while two fingers of his other hand engage the portions 35 and 3| of the levers 25 and 26. When the blade is located in its proper position over the safety razor, the user presses against the portions 35 and 3|, thus causin the levers 25 and 26 to swing around their pivots and release the blade 5, which drops into the proper position upon the safety razor. As soon as the pressure upon the levers 25 and 26 is released, the springs 33 and-34 cause them to resume their original positions which are shown in Figure 3.

It is apparent that the'specific illustrations shown above havev been given by way of illustration and not by way of limitation, and that the structures'above described are subject to wide variation and modification without departing from the-scope or intent of the invention, all of which variations and modifications are to be included within the scope of the present invention.

What'is claimed is:

Blade supporting means, comprising a separate independent support for each'single razor blade; said'support consisting of a thin substantially rectangular piece of resilient metal having a flat supporting surface for carryin 'a single razor blade, said supporting surface being somewhat wider than the razor blade to protect the cutting edges thereof, and two curved flaps which are integral with the resilient support and which are situated opposite each other close to opposite edges of thesupport at a' distance enabling said flaps to overlap opposed tongue portions of the blade, at least one notch being formedin said support close to a flap, said notch extending in' the longitudinaldirection of the flap, whereby a blade held by said flaps may be released by bending those portions of the resilient support which are adjacent to said opposed'fedges. v
